Question

wheel of a motorcycle travel 396 metre in 150 Revolution . find the radius and diameter of the wheel.​

Answer 1

Step-by-step explanation:

In 150 revolutions it travels 396 m

Therefore, in one revolution it will cover=396/150=2.64 m

Therefore, circumference C =2.64 m

$c = 2\pi \: r \\r = \frac{2.64 \times 7}{2 \times 22} = 0.42 \: m \\ d = 0.84 \: m$

Answer 2

Answer:

150 revolutions it travels 396 m

Therefore, in one revolution it will cover=396/150=2.64 m

Therefore, circumference C =2.64 m

\begin{lgathered}c = 2\pi \: r \\r = \frac{2.64 \times 7}{2 \times 22} = 0.42 \: m \\ d = 0.21 \: m\end{lgathered}

c=2πr

r=

2×22

2.64×7

=0.42m

d=0.21m
